The Hanen Program® – The beauty of the ‘4 S’

ByLondon Speech and Feeding

One of my favourite pieces of advice I give to parents is the ‘4 S’, a strategy coined by the Hanen Program® which I teach, particularly the ‘More than Words’ programme which is designed for and aimed at parents of children with Social Communication Difficulties or Autism. It is honestly one of those golden nuggets that I use myself in my practice and I highly recommend it to all my parents. There is something about terms like the ‘4 S’ that is easy to recall and therefore use.

Introduction

The ‘4 S’ is a strategy that helps to clarify the words we use with our children so that they can notice us, hear us and understand what we are saying.

Research shows that we use on average 120-200 words per minute during everyday conversation. That’s a lot! And our children who are still learning to communicate are often bombarded with endless speech coming at them all day long. If we take into account that many of our students are Gestalt Language Processors, we can see that picking out relevant chunks of what we are saying is not at all easy, and this contributes to our children’s delays.

So let’s look at the ‘4 S’

1. The first one is SAY LESS

This means we should use shorter, simpler sentences with good grammar, for example, something like: ‘let’s get ready, time to put our shoes on’ instead of what we might be saying: ‘come on then darling, let’s put your shoes on we need to get going it’s dark outside’ or similar.

Good grammar helps to give clues about what words mean and how they are used in sentences. So, instead of ‘shoes on’ say ‘let’s put our shoes on’.

2. The second one is STRESS

I hear you think ‘I am stressed!‘. – NO! here it means ‘highlight’. We use our voice to highlight the important words in our sentence or phrase. For example, when you say ‘this banana is so yummy’ you can stress the word ‘yummy’ by saying it a bit louder and you can make a gesture, like rubbing your tummy as you say it.

3. The third one is GO SLOW

This means to speak a bit slower than you normally would and add pauses. By slowing down the pace of our speaking we give our child time to think and understand what we are saying. When we allow for pauses after we have spoken, we are inviting our child to say something in response.

4. The last one is SHOW

Always remember to show actions, gestures, objects, and point to pictures while speaking to help support your child’s understanding. We can show our child what words mean by pointing to things or holding up objects whilst describing or talking about them.

At this point I would also like to recommend the use of Core Boards, and particularly Electronic AAC devices, such as LAMP Words for Life or PODD. I have written about this in other blogs but can always be persuaded to say a bit more on the matter… 😊 It is such a big help to have an AAC talker available for both the child and the adult so we can find words and pictures to help support the words we are saying.

For example, today when reading a book like The Hungry Caterpillar (so good!) I used my LAMP AAC talker to make comments as we were looking at the pages together with my student. Example: ‘Look! He is eating more cake he is very hungry’ using my AAC talker I was able to supplement my speech and at the same time I was inviting my minimally speaking child to press a button or two and reply with ‘cake!’ which they would not have said with their mouth otherwise.

5. It does say ‘4 S’ but really it should be ‘5’ except the fifth is not an ‘S’

The fifth is REPEAT.

Repeat words and phrases often throughout the day. When learning a language we all need to hear words and phrases several times and in different situations before we can understand, remember, and then eventually use them. Our children are ‘new language learners’ and so we can apply the same principles that we would when learning a new foreign language ourselves.

  • What is FRONTING?

    ByLondon Speech and Feeding
    Kids Speech Therapist London

    Does your child say “Dough” instead of “Go”? Or “Tea” instead of “Key”? Do you hear a /Sh/ instead of an /S/ does “see” sound more like “she”?

    We Speechies call this a Fronting Pattern which means that a sound that should be produced at the back of the throat with the back of the tongue, like K or G , is said at the front of the mouth with the tip of the tongue, like a T or a D or SH. When this happens speech can be really hard to make out because these sounds are literally everywhere in everyday sentences. Just think how many K’s and G’s we hear in a simple sentence?

    For example, I heard my little student say earlier today: “I know what game we can play in your garden? It’s the one with cones and rings and cushions! I know where it is I can get it.”

    But it sounded like:

    “I know what DAME we DAN play in the DARDEN! It’s the one with TONES and rings and TUSHIONS! I know where it is I TAN DED it.”

    If that sounds familiar to you, here is a little overview of what we can do about it:

    First up it’s always good to start with general speech sounds awareness: does a child hear syllables and intonation? Do they know words that rhyme? Can they follow or copy a simple beat with a drum? Can they listen and hear quiet sounds and loud sounds and can they copy those? Can they follow mouth and tongue movements:, for example : stick out your tongue, lick your lips, click your tongue, blow raspberries?

    Then it really helps to talk about BACK and FRONT of things and to draw attention to the back of the mouth and the back of the tongue and the front tip of the tongue and how sounds are made in the mouth. I often use a puppet to show this or a model of a mouth like this one here in the picture.

    Next we try and listen to words starting with a BACK sounds like a K or a G , and I read out a list of words with those sounds: COW, CORE, CAT, CONE, KEY etc or ARK, EEK, OAK, ACHE…

    Or GOO GUY GUM GONE

    After that we try and see if a student can actually produce a single sound like a K or a G just by itself. If they can, that’s a really great start and if they can’t I help them to produce one – over a few sessions we usually get there. We call this Sound production in isolation.

    Once a child can produce a sound correctly, on its own, we try and start working on very simple words that are really powerful like “GO”!!!!! in a motivating game or “CAR” for little ones who love a car racing track.

    Now that we have established the back sounds and are using it in short words, we can gradually re-train brain pathways and oral- motor/movement pathways to use these new sounds in many words and then short phrases. That can take time!! This is called generalisation and it is not uncommon for it to take up a whole year for fluent speech to be error-free .

    Why does it take so long? Being able to produce a correct and clear K or G sound does not mean it will be used easily. Our brain pathways are fixated or habituated to the error sound. It takes time for habits to change. A child might be able to hear the word TIGER with a G in the middle and she knows that it is not a TIDER but when saying it her tongue automatically moves forward rather than lifts up at the back. It’s a bit like a person who has a rounded back: the brain knows to stand upright and how not to slouch, but when we don’t focus on it, ooops we have slouched again because that is what we are comfortable doing and our body moves with our habit.

    It takes effort and motivation to change our movement patterns and that includes our tongue and lip patterns! We usually get there through a huge variety of games and practice. Lots and lots of repetition is key as is motivation to change.

    Parents and carers are crucial in the success of Speech Therapy!

    We need your feedback at home, the regular short and sweet exercises, the constant positive encouragement and great modelling of speech sounds. We often find that parents are tuned into their child’s error sounds and can understand them much better than anyone else. This is great of course in many ways, however, it also means that the child has less motivation to change: if mummy understands me then my world is ok.

    I will give you a short outline of what different speech therapy models I use in my practice, be it in clinic face to face or on-line in my future blogs soon.

    Discover nine ways to support literacy in autistic children

    ByLondon Speech and Feeding

    We are all aware that Autism is on a spectrum. By the very nature of this, it means that every child will present differently, so an individualised approach is required. We need to remember to use a child’s strengths to support their needs. By using a person-centred approach, you’ll see your child’s literacy develop and thrive.

    I hear many parents concerns about literacy as well as communication. Will they be able to read, write and spell? How will they manage their literacy independently? The questions are endless, so let’s look at how you can support your child’s literacy skills and how together we can provide a scaffold to them becoming independent learners.

    1. The one thing we know is that Autistic children are visual learners. They succeed by us sharing pictures and demonstrating how the narrative is shown.
    2. Start reading to your child at an early age. You can never start too early. This creates a love for books and supports vital pre-literacy skills (such as increasing vocabulary, following narratives, awareness of sounds in words, and letter recognition and awareness). By supporting pre-literacy skills, you’re starting the process to create confident young readers.
    3. There are many ways to use books. You can narrate the story using different voices and tones to increase interest. You can do this even if your child isn’t interested. They are still listening and learning vital skills. You may even ask and answer questions and voice the skills that they will need for internal monitoring.
    4. Use their interests to select appropriate reading material. In addition, you can then create questions on the book and provide a scaffold to support your child with the answer.
    5. Use technology to spark their interest in reading. Demonstrate how they can read online. This is often successful as it becomes an individual activity as opposed to needing social interaction.
    6. Provide them with a choice of texts (e.g., would you like ‘Perfectly Norman or when things get too loud’) rather than an open-ended question such as ‘What book would you like to read?’
    7. Write key pieces of information down on paper. Research suggests that Autistic learners understand written text better than speech.
    8. You could have a ‘word of the day’ from chosen reading material that you explore together.
    9. Reading aloud to your child can have many benefits which include understanding vocabulary to how the book is read, with appropriate intonation.

    I highly recommend the boom decks as they are a great resource!

    “If they can’t learn in the way we teach, then we teach the way they learn”

    The quiet power: Why silence and responsiveness boost communication in children with delays

    ByLondon Speech and Feeding
    The quiet power: Why silence and responsiveness boost communication in children with delays
    Supplied by Sonja McGeachie, Practice Owner

    As parents and caregivers, our natural instinct when interacting with a child, especially one who struggles with communication, is often to fill every silence. We might ask lots of questions, offer constant commentary, or try to prompt him or her to speak. Our hearts are in the right place. We want to help him or her communicate! However, for children with language delays or those on the autism spectrum, this well-intentioned approach can sometimes inadvertently create more pressure and fewer opportunities for them to truly initiate and develop their own communication skills.

    What if I told you that one of the most powerful tools in your communication toolkit is often silence? And that responding to your child, rather than always initiating, can unlock incredible potential?

    Let’s explore why these seemingly simple strategies are so profoundly beneficial.

    The unspoken benefits of silence

    In our fast-paced world, silence can feel awkward, but for a child who is processing language differently, it’s a gift:

    1. Time to process: Children with language delays often need more time to process what they hear and to formulate their own thoughts or responses. When we bombard them with words, we don’t give their brains the crucial milliseconds they need to catch up. A pause of 5–10 seconds can make all the difference.
    2. Reduces pressure: Constant questioning or prompting can feel like a test. Silence removes this pressure, creating a more relaxed environment where the child feels safe to communicate without fear of being ‘wrong’ or rushed.
    3. Creates opportunity to initiate: If you’re always talking, when does your child get a turn to start the conversation? Silence opens up a space for him or her to initiate, whether it’s through a sound, a gesture, eye contact, or a word. This is vital for developing spontaneous communication.
    4. Encourages independent thinking: When a child is given space, he or she is more likely to try to figure things out himself or herself. This fosters problem-solving skills and reduces reliance on adult prompts.
    5. Prevents overwhelm (especially for ASD): Many children on the autism spectrum can be sensitive to auditory input. A constant stream of language can be overwhelming, leading to withdrawal or challenging behaviours. Strategic pauses can help them regulate and engage more effectively.

    The power of responding (not just initiating)

    Think of a tennis match: if only one person serves, it’s not a game. Communication is a rally, a back-and-forth exchange. When you primarily respond to your child’s communication attempts, you’re teaching him or her the rhythm of conversation:

    1. Follow the child’s lead: This is a cornerstone of effective language intervention, famously championed by programs like Hanen’s ‘It Takes Two to Talk’. When you respond to what your child is already interested in or doing, the interaction becomes immediately relevant and motivating for him or her.
    2. Validates his or her attempts: Every sound, gesture, glance, or partial word your child offers is a communication attempt. By responding to it, you’re telling him or her, ‘I see you. I hear you. Your communication matters.’ This builds immense confidence and encourages him or her to try again.
    3. Builds confidence and motivation: When a child feels understood and successful in his or her communication, he or she are more likely to communicate more often. It’s a positive feedback loop.
    4. Teaches turn-taking naturally: By taking your turn after his or hers, you model the natural flow of conversation. He or she learns that communication is a shared activity, not a one-sided lecture.
    5. Makes interactions meaningful: When you respond to his or her interests, you’re talking about things that are inherently motivating to him or her. This makes the language you use more easily understood and remembered.

    Practical strategies for parents: Observe, Wait, Listen (OWL)

    The Hanen Centre’s ‘Observe, Wait, Listen’ (OWL) strategy perfectly encapsulates these principles:

    • Observe: Watch your child closely. What is he or she looking at? What is he or she doing? What sounds is he or she making? What gestures is he or she using?
    • Wait: After you’ve observed, wait. Give him or her time. Resist the urge to jump in with a question or comment immediately. Count to five (or even ten) in your head. This silence is an invitation for him or her to communicate.
    • Listen: When he or she does communicate (in any way!), listen intently. Try to understand his or her message or intent.

    Beyond OWL – More tips:

    • Reduce questions, increase comments: Instead of ‘What’s that?’ try ‘Oh, a big red ball!’ or ‘The car is going fast!’ Comments provide language models without demanding a verbal response.
    • Expand, don’t just prompt: If your child says ‘Car’, you could respond with ‘Yes, That’s a big car!’ or ‘It’s really fast!’ You’re building on his or her communication with a slightly richer language model.
    • Create opportunities for communication: Place desired items slightly out of reach. This creates a natural reason for your child to communicate his or her wants (e.g., reaching, pointing, vocalising).
    • Respond to all communication: Don’t just wait for words. If your child points, look where he or she is pointing and comment. If he or she makes a sound, imitate it or respond with a related word.

    In summary

    Embracing silence and prioritising responsiveness might feel counterintuitive at first, especially when you’re eager for your child to talk. However, these powerful strategies create a nurturing, low-pressure environment that encourages spontaneous communication, builds confidence, and truly meets your child where he or she is. By giving your child the space and the meaningful responses he or she needs, you’re laying a strong foundation for his or her communication journey.

    Try incorporating these ‘quiet powers’ into your daily interactions and watch your child’s communication blossom.

    Understanding phonological processes in 3–7-year-olds: What’s typical and when to seek help

    ByLondon Speech and Feeding

    As a speech and language therapist, one of the most common questions I hear from parents is:

    ‘They can talk, but their speech still sounds immature. Is this normal?’

    Many children between the ages of three and seven use speech patterns that make their words sound different from adult speech. These patterns are known as phonological processes, and for younger children, they are a normal part of speech development.

    However, when these processes persist beyond the expected age, they can start to affect clarity, confidence and learning, especially once children enter school.

    This blog will help you understand:

    • what phonological processes are
    • which patterns are typical at different ages
    • and when it might be time to seek speech therapy support

    What are phonological processes?

    Phonological processes are patterns of sound simplification that children use while their speech system is developing.

    Instead of learning each sound one by one, children initially organise sounds into patterns that make speech easier to produce. This is a normal and efficient strategy for a developing brain.

    For example:

    • saying ‘tar’ instead of ‘car’
    • saying ‘poon’ instead of ‘spoon’
    • saying ‘bud’ instead of ‘bus’

    These are not ‘bad habits’. They are part of how speech develops.

    The key question is how long these patterns last.

    Common phonological processes (and when they usually disappear)

    Below are some of the most common processes parents notice in 3–7-year-olds.

    1. Final consonant deletion

    Leaving off the last sound in a word

    • ‘ca’ for cat, ‘da’ for dog
    • Typically resolved by 3–3½ years

    2. Fronting

    Replacing back sounds (k, g) with front sounds (t, d)

    • ‘tar’ for car, ‘do’ for go
    • Typically resolved by 3½–4 years

    3. Cluster reduction

    Omitting one sound in a consonant cluster

    • ‘poon’ for spoon, ‘top’ for stop
    • Typically resolves by 4–5 years (some clusters slightly later)

    4. Gliding

    Replacing /R/ or /L/ with /W/ or /Y/

    • ‘wabbit’ for rabbit, ‘yion’ for lion
    • Can be typical up to 5–6 years

    5. Weak syllable deletion

    Leaving out unstressed syllables

    • ‘nana’ for banana
    • Usually resolved by 4 years

    If these patterns continue past the expected age, speech can remain difficult to understand particularly for unfamiliar listeners such as teachers, peers, and also Auntie Karen or grandparents who visit once in a while.

    Why phonological processes matter in school-age children

    By the time children reach reception and Year 1, speech clarity becomes increasingly important.

    Persistent phonological difficulties can affect:

    • being understood by teachers and peers
    • phonics and early reading
    • spelling
    • confidence in speaking
    • willingness to participate in class

    Some children become aware that they ‘sound different’ and may speak less, avoid longer words, or become frustrated when misunderstood.

    What’s the difference between a delay and a disorder?

    This is an important distinction.

    • A phonological delay means a child is following the normal pattern of development, just more slowly.
    • A phonological disorder means the child is using atypical patterns, or continuing age-expected patterns well beyond when they should have resolved.

    A speech and language assessment helps identify:

    • which processes are present
    • how many are affecting speech
    • how consistent the errors are
    • and whether intervention is needed

    Signs it may be time to seek speech therapy

    You may want to seek professional advice if your child:

    • is 3½ years or older and still hard to understand
    • is understood well by family but not by others
    • becomes frustrated or avoids talking
    • has difficulty with phonics or spelling
    • uses several phonological processes at once
    • has not made progress despite time and encouragement

    Early support does not mean something is ‘wrong’. It simply helps speech development move forward more efficiently.Research consistently shows that unresolved phonological processes beyond the expected age can impact intelligibility, literacy and confidence (Dodd, 2014; Bowen, 2015).

    How speech therapy helps phonological development

    Phonological therapy is not about drilling individual sounds endlessly.

    Instead, therapy focuses on:

    • helping children recognise sound patterns
    • building awareness of contrasts (e.g. ‘tar’ vs ‘car’)
    • practising speech in meaningful, playful ways
    • supporting generalisation so progress carries into everyday speech

    For school-aged children, therapy is usually structured, motivating and highly targeted and progress can be very encouraging.

    A final reassurance

    Many children with phonological difficulties go on to develop clear, confident speech with the right support.

    If you’re unsure whether your child’s speech is ‘just a phase’ or something that needs attention, a professional assessment can give clarity and peace of mind.

    If you’d like support or advice, please contact me and I can help guide the next steps.

  • Why I love ‘Colourful Semantics’ in speech therapy

    ByLondon Speech and Feeding

    One of the most common concerns parents bring to speech and language therapy is:
    ‘My child understands so much… but they struggle to put sentences together’.

    Some children use only single words.
    Others miss out key parts of sentences.
    Some mix up word order.
    Others find it difficult to answer questions or explain their ideas clearly.

    This is where one of my favourite therapy approaches can be incredibly powerful: Colourful Semantics.

    Colourful Semantics is a highly effective and evidence-informed way of supporting children to build stronger sentence structure, grammar, understanding, and expressive language skills.

    It is a visual approach to language development originally created by a UK Speech and Language Therapist, Alyson Bryan in 1997 to help children understand how sentences are organised.

    Different parts of a sentence are represented by different colours.

    For example:

    • Who? is orange.
    • What doing? is yellow.
    • What? is green.
    • Where? is blue.

    As children progress more colours are added:

    • To Whom? Is pink.
    • Adjectives (what like) is purple.
    • Time Phrase is brown.

    Using colours gives children a visual framework for building sentences in a way that feels structured, predictable, and achievable.

    Instead of language feeling abstract and overwhelming, children can see how sentences fit together.

    For many children, this is massively helpful as it gives structure and predictability.

    Why some children struggle with sentences

    Language development is incredibly complex.

    To build a sentence, we need to:

    • think of vocabulary
    • organise grammar
    • sequence words
    • understand meaning
    • remember sentence structure
    • physically say the words clearly enough to communicate

    That is a huge amount happening all at once.

    Some children may:

    • leave out verbs
    • miss pronouns
    • use immature grammar
    • struggle with word order
    • rely on very short phrases
    • find it difficult to expand beyond single words.

    For example:

    • ‘Boy jump’
    • ‘Him eating’
    • ‘Dog there’
    • ‘Want juice’.

    These children often know more than they can express.

    Colourful Semantics helps bridge that gap.

    Why visual supports matter

    Many children—especially those with language delays, developmental language disorder (DLD), autism, or social communication difficulties—benefit enormously from visual support.

    Visual systems reduce the processing load.

    Instead of relying only on spoken language, children are given an additional way to organise information.

    The colours act almost like ‘anchors’ for language.

    A child may begin to understand:

    • orange = who
    • yellow = action
    • green = object
    • blue = place.

    This makes sentence building more concrete and less overwhelming.

    It also supports children who struggle with:

    • attention
    • auditory memory
    • processing spoken language
    • sequencing
    • confidence using language independently.

    Supporting sentence expansion naturally

    One of the things I love most about Colourful Semantics is how flexible it is.

    It can be used:

    • in play
    • with books
    • during conversation
    • with picture scenes
    • in storytelling
    • during movement activities
    • within everyday routines.

    Therapy does not need to feel rigid or worksheet-heavy.

    Many children who usually avoid talking become much more willing to attempt longer sentences when they feel successful.

    Children often begin to use:

    • verbs more accurately
    • pronouns more consistently
    • better word order
    • improved sentence organisation
    • and more complete ideas.

    For example, instead of:

    • ‘Him running’

    A child may gradually move toward:

    • ‘He is running.’

    The colours help children understand the ‘jobs’ words have within a sentence.

    This is particularly useful for children who need explicit teaching of language structure rather than simply learning through exposure alone.

    Supporting children with speech difficulties too

    One thing I particularly value in therapy is approaches that support multiple communication areas at once.

    Colourful Semantics is excellent for this.

    While building sentences, we can also naturally target:

    • speech sounds
    • intelligibility
    • vocabulary
    • social communication
    • turn-taking
    • attention and listening
    • confidence speaking.

    For example, if a child is working on the /K/ sound, we might intentionally build sentences containing target words:

    • ‘The cat is coming.’
    • ‘The boy is kicking.’
    • ‘The duck is in the box.’

    This allows speech and language goals to work together rather than separately.

    Therapy becomes more functional, meaningful, and engaging.

    Building confidence through success

    One of the biggest barriers many children experience is not simply language difficulty. It is the emotional impact of struggling to communicate.

    Some children become frustrated.
    Others withdraw.
    Some stop attempting longer sentences altogether because communication feels too hard.

    Colourful Semantics can help rebuild confidence because it gives children a clear structure for success. That feeling matters enormously.

    When children feel successful, they participate more.
    They attempt more.
    They communicate more.

    And communication grows through communication.

    Why I use colourful semantics

    There is no single ‘magic’ therapy approach for every child.

    But Colourful Semantics remains one of the most versatile and effective tools I use because it can be adapted so beautifully to individual children.

    It supports:

    • early language
    • grammar
    • sentence structure
    • comprehension
    • expressive language
    • storytelling
    • confidence
    • functional communication.

    Most importantly, it helps children organise language in a way that finally starts to make sense to them.

    And when language starts to make sense, communication can truly begin to flourish.

    The hidden impact of mouth breathing and open mouth posture on speech and feeding

    When most people think about speech or feeding difficulties, they picture the tongue, lips, or chewing skills, but how a child breathes at rest plays a surprisingly big role too.

    Mouth breathing and open mouth resting posture can quietly influence everything from how a child’s face grows to how clearly they speak, to how confidently they chew and swallow. It’s something many parents never think about, until they start noticing the subtle signs.

    Let’s explore why this happens, what to look for, and how to gently support better breathing and oral posture.

    Recent research supports this link between mouth breathing and speech difficulties. For example, a 2022 study by Alhazmi et al., published in the Journal of Pharmacy and Bioallied Sciences, found that 81.7% of children aged 9–17 who breathed primarily through their mouths presented with speech sound disorders. The study highlights how mouth breathing can significantly influence orofacial development and articulation patterns.

    💨 Why we’re designed to breathe through our nose

    Our bodies are made for nasal breathing. When we breathe through the nose, the air is filtered, warmed, and humidified before reaching the lungs. The tongue naturally rests against the roof of the mouth, the lips close gently, and the jaw stays relaxed, all of which encourage healthy oral development.

    In contrast, mouth breathing often means the tongue rests low in the mouth and the lips stay apart. Over time, this posture can subtly reshape how the muscles and bones of the face grow.

    Children who breathe through their mouths most of the time may develop:

    • A longer face and narrower palate
    • Forward head posture
    • Slightly open lips and low tongue position at rest
    • A tendency toward drooling or noisy breathing
    • A dry mouth and consequently bad breath
    • At times the tongue pushes constantly against the front teeth causing them to grow forward (buck teeth)

    These changes are not anyone’s fault, as they often start because of blocked noses, allergies, enlarged adenoids, low facial muscle tone or habits formed when a child was younger. But understanding the pattern helps us know how to support change.

    🗣 How mouth breathing affects speech

    Speech depends on precise coordination between the lips, tongue, and jaw. The resting position of these structures affects how ready they are to move.

    1. Reduced tongue strength and placement, i.e. the tongue rests low in the mouth (as it does in mouth breathing), it’s harder for children to lift it efficiently for sounds like /T/, /D/, /N/, /L/, and /S/. This can lead to speech that sounds slightly slushy or unclear, or a frontal lisp.
    2. Open mouth posture and resonance: An open mouth at rest may affect how air vibrates in the oral and nasal cavities. Children might have speech that sounds a bit ‘muffled’ or lacks crispness because the lips and jaw aren’t fully supporting articulation.
    3. Fatigue and breath control: Mouth breathing can lead to drier mouths and less efficient breath support. That can make longer sentences or conversations feel tiring, especially in noisy environments.

    🥄 How mouth breathing affects feeding and chewing

    Feeding involves the same structures that control speech, so posture and breathing patterns matter here, too.

    1. Chewing efficiency: Children who habitually keep their mouths open often have low tongue tone and reduced jaw stability. They may prefer softer foods, chew slowly, or struggle with mixed textures.
    2. Swallowing pattern: A tongue that rests low may push forward when swallowing. This ‘tongue-thrust swallow’ can interfere with efficient chewing and even affect dental alignment over time.
    3. Breathing while eating: Since it’s hard to chew, swallow, and breathe through the mouth simultaneously, children who can’t comfortably nasal breathe may rush bites or pause to catch their breath. This can contribute to coughing, choking, or food refusal.

    Common signs to watch for

    Parents often notice subtle clues before realising mouth breathing is a pattern. Some red flags include:

    • Lips habitually open at rest
    • Drooling after the toddler years
    • Snoring or noisy breathing during sleep
    • Preference for soft foods or grazing eating habits
    • Dark circles under the eyes due to allergies
    • Frequent colds, congestion, or mouth odour
    • Speech that sounds slushy or unclear despite good effort

    If several of these sound familiar, it’s worth mentioning them to your child’s GP, dentist, or speech and language therapist.

    👩‍⚕️ What can help

    1. Address the underlying cause: If nasal blockage, allergies, or enlarged adenoids are making nasal breathing difficult, a medical assessment is the first step. ENT specialists can rule out or treat physical causes.
    2. Encourage closed mouth rest: Gentle reminders like ‘Lips together, tongue up, breathe through your nose’ can help older children become aware of their resting posture. For younger ones, visual cues (stickers or mirrors) can make it a game.
    3. Build oral-motor strength and awareness: Speech therapists can design activities to strengthen the tongue and lips, improve jaw stability, and encourage balanced breathing. This might include blowing games, tongue-tip lifts, use of dental-palatal devices or oral-motor exercises disguised as play.
    4. Support good posture: Sometimes mouth breathing goes hand-in-hand with forward-head posture. Encouraging upright sitting during meals and screen time helps keep the airway open and supports better breathing habits.
    5. Make nasal breathing part of daily routines: Gentle nose-breathing practice during calm times (reading, bedtime, car rides) helps normalise it. Avoid making it a battle: calm, consistent reminders work best.

    🌱 A gentle note on change

    Patterns of mouth breathing develop over time, and change doesn’t happen overnight. It’s important to approach this with curiosity, not criticism. The aim isn’t ‘perfect breathing,’ but to give your child the tools and awareness to breathe comfortably and efficiently.

    Small improvements in nasal breathing and resting posture can lead to big gains in speech clarity, eating confidence, and even sleep quality.

    💡 The takeaway

    Breathing seems automatic, and it is! but how we breathe matters. Mouth breathing and open-mouth posture can quietly shape how a child speaks, eats, and grows.

    By noticing early signs, addressing underlying causes, and building supportive habits, you can help your child move toward stronger, clearer speech and more comfortable mealtimes.

    Just like every area of development, progress starts with connection, patience, and gentle consistency, one calm breath at a time.
